Tested with FC3 and newer, here's a way to configure your SCSI scanner.

Login as root and probe for your scanner:

$ su - root
password:
# modprobe sg

This creates the scanner file /dev/sg0.
Set the permissions to 777 for everybody:

# chmod 777 /dev/sg0

Copy the file to the (new) udev location so it's available after the next reboot:

# cp -a /dev/sg0 /etc/udev/devices

Change ownership of the file to root:

# chown root.root /etc/udev/devices/sg0

Edit the appropriate Sane config file (filename depends on the brand scanner you're using):

# vi /etc/sane.d/hp.conf

Set the pointer to the sg0 file:

scsi HP
# The usual place for a SCSI-scanner on Linux
/etc/udev/devices/sg0

And your done
Happy scanning!
